DESCRIPTION
If the cam position signal pulse sent from the ECM via a direct line is abnormal, the motor generator control ECU (MG ECU) (built into the inverter with converter assembly) stores DTC P034000 or P034031.

Waiting for at least 10 minutes is required to discharge the high-voltage capacitor inside the inverter with converter assembly.
*a | Without waiting for 10 minutes |
NOTICE:
After turning the power switch off, waiting time may be required before disconnecting the cable from the negative (-) auxiliary battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) auxiliary battery terminal notices before proceeding with work.

CAUTION:
Be sure to wear insulated gloves.
(a) Check that the service plug grip is not installed.
NOTICE:
After removing the service plug grip, do not turn the power switch on (READY), unless instructed by the repair manual because this may cause a malfunction.
(b) Disconnect the A58 inverter with converter assembly connector.
(c) Disconnect the A26 ECM connector.
